This week in our Tuesday class we continued to learn about simple machines by learning about gears. Gears can be classified by the number of teeth. The teeth of the gears mesh together to create movement. A crown gear is a special gear that meshes with a regular gear at a 90-degree angle. An example can be seen below.

On Monday, November 10th we will be heading down to LegoLand for a big event. It's the CHALLENGE REVEAL At this event we will find out what the Jr. First Lego League Challenge is and begin to think of what our next steps will be. In addition, highly trained LegoLand specialists will be engaging us is a Lego Brick build where we will learn how to program sensors. How exciting is that?
